Previously,\nset_output_gamma was being checked for null, but then it was being\ndereferenced without any null check. This could lead to a null pointer\ndereference if set_output_gamma is null.\n\nTo fix this, we now ensure that set_output_gamma is not null before\ndereferencing it. We do this by adding a null check for set_output_gamma\nbefore the call to set_output_gamma."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/display/dc/hwss/dcn32/dcn32_hwseq.c"],"versions":[{"version":"235c67634230b0f9ad8c0185272fed36c892b1c4","lessThan":"e087c9738ee1cdeebde346f4dfc819e5f7057e90","status":"affected","versionType":"git"},{"version":"235c67634230b0f9ad8c0185272fed36c892b1c4","lessThan":"f38b09ba6a335c511eb27920bb9bb4a1b2c20084","status":"affected","versionType":"git"},{"version":"235c67634230b0f9ad8c0185272fed36c892b1c4","lessThan":"496486950c3d2aebf46a3be300296ac091da7a2d","status":"affected","versionType":"git"},{"version":"235c67634230b0f9ad8c0185272fed36c892b1c4","lessThan":"5298270bdabe97be5b8236e544c9e936415fe1f2","status":"affected","versionType":"git"},{"version":"235c67634230b0f9ad8c0185272fed36c892b1c4","lessThan":"28574b08c70e56d34d6f6379326a860b96749051","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/gpu/drm/amd/display/dc/hwss/dcn32/dcn32_hwseq.c"],"versions":[{"version":"6.0","status":"affected"},{"version":"0","lessThan":"6.0","status":"unaffected","versionType":"semver"},{"version":"6.1.120","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.64","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.10.14","lessThanOrEqual":"6.10.*","status":"unaffected","versionType":"semver"},{"version":"6.11.3","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.1.120"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.6.64"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.10.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.11.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0","versionEndExcluding":"6.12"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/e087c9738ee1cdeebde346f4dfc819e5f7057e90"},{"url":"https://git.kernel.org/stable/c/f38b09ba6a335c511eb27920bb9bb4a1b2c20084"},{"url":"https://git.kernel.org/stable/c/496486950c3d2aebf46a3be300296ac091da7a2d"},{"url":"https://git.kernel.org/stable/c/5298270bdabe97be5b8236e544c9e936415fe1f2"},{"url":"https://git.kernel.org/stable/c/28574b08c70e56d34d6f6379326a860b96749051"}],"title":"drm/amd/display: Add NULL check for function pointer in dcn32_set_output_transfer_func","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-49909","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-10-22T13:41:51.958050Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-22T13:48:46.409Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"}],"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2025-11-03T20:41:53.950Z"}}]}}
